Large Diameter Stringing Block with Integrated Grounding Roller for OHTL Safety

Large Diameter Stringing Block with Integrated Grounding Roller for Enhanced Overhead transmission line (OHTL) Safety & Efficiency

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we prioritize both operational efficiency and, critically, the safety of personnel during power line construction. Our Large Diameter Stringing Block with an Integrated Grounding Roller is a specialized, high-performance tool meticulously engineered to provide superior guidance for conductors while simultaneously mitigating hazardous electrostatic buildup during tension stringing operations. As a prominent China manufacturer and exporter, we offer a comprehensive one-stop supply for a wide array of tools and equipment for power lines, and this innovative block exemplifies our unwavering commitment to advanced safety features, robust design, and reliable performance for high-voltage overhead transmission line (OHTL) projects.

During the stringing of long conductors, especially in dry conditions or near energized lines (live-line stringing), significant electrostatic charges can accumulate on the conductor. This poses a serious safety risk to workers. Our large diameter stringing block addresses this by incorporating a dedicated grounding roller within its design. This feature ensures a continuous electrical path from the conductor to a safe ground, effectively dissipating static charges and enhancing worker safety. The large diameter sheave also minimizes bending stress on heavy conductors, preserving their integrity during installation.

Product Features & Benefits:

• Integrated Grounding Roller: The standout feature, providing a continuous, reliable electrical connection from the conductor to the block frame and a ground wire, safely dissipating electrostatic charges and induced currents, significantly enhancing worker safety.

• Large Sheave Diameter: Minimizes the bending radius of the conductor, reducing internal stresses, preventing deformation, and preserving the integrity of expensive conductors, particularly crucial for large diameter or high-voltage lines.

• High Load Capacity: Robustly constructed to handle substantial tension loads associated with heavy conductors used in extra-high voltage (EHV) and ultra-high voltage (UHV) transmission lines.

• Smooth & Efficient Operation: Equipped with high-quality, sealed precision bearings that ensure exceptionally smooth and low-friction rotation, facilitating effortless conductor pulling while reducing wear on both the block and the conductor.

• Superior Conductor Protection: Features a precisely engineered groove, often lined with durable, non-abrasive materials like UMC (polyurethane) or resilient rubber, providing a gentle contact surface to protect the conductor from kinking, abrasion, or other costly damage.

• Durable & Robust Construction: Manufactured from high-strength galvanized steel and/or robust aluminum alloys, built to withstand the rigors of continuous field use and harsh environmental conditions, guaranteeing extended service life.

• Corrosion Resistance: All exposed components are typically hot-dip galvanized or treated with durable coatings, providing excellent protection against rust and environmental degradation.

Product Applications:

Our Large Diameter Stringing Block with an Integrated Grounding Roller is indispensable for a wide range of critical overhead transmission line projects, especially where safety and conductor integrity are paramount:

• High-Voltage & Extra-High Voltage (EHV/UHV) Line Construction: Essential for stringing large, heavy conductors where electrostatic buildup is a significant concern.

• Live-line stringing Applications: Provides a crucial safety measure when stringing operations are performed in proximity to energized lines.

• Long Span & River Crossing Projects: Minimizes bending stress on conductors over extended spans while ensuring continuous grounding.

• Re-conductoring & Line Upgrades: Ideal for replacing or upgrading conductors on existing lines, prioritizing worker safety.

• Areas Prone to Thunderstorms: Provides added protection in regions susceptible to lightning activity during construction.

• Any Project Requiring Enhanced Safety Protocols: A vital tool for companies adhering to the highest safety standards for electrostatic discharge.
